EMC Centera: Designing a Content-addressable Government-compliant Object Store Cluster
The combination of object-based storage model, content addressability and verification offers a set of unique features for storing fixed content. When such storage systems also leverage cost-effective commodity HW with high-capacity desktop-class disk drives, they can offer applications functions not possible with traditional (i.e., block-based or file-based) on-line storage systems. In addition to offering per-object retention and protection policies and extensible attributes, such on-line content-addressable systems can also satisfy government-compliant regulations for archiving digital information traditionally achieved only by laser disk juke-boxes or tape silos.
This talk will present one realization of such an architecture: EMC Centera. It will describe Centera's high-level architectural features and illuminate the motivation behind some of the design decisions and the challenges of using commodity components and high-capacity desktop disk drives. Finally, it will describe the delicate balance between shipping a product vs.. getting the design 100% right as well as the implications of ever-changing workload and access patterns on the overall architecture of the system.
Jiri Schindler is a principal system architect in the EMC's Centera storage platform group. His primary responsibilities are design and end-to-end performance characterization of Centera core services. He is also an adjunct professor at Northeastern University in Boston where he teaches a storage systems class. He received his PhD from Carnegie Mellon University in 2004, where he spent 6 years prior to coming to EMC.
